Looks like you have a Benchmark metal bi-fold door. The photo you are showing resembles our 21-209 the pivot bracket with a 21-044 spring loaded bifold pin. Our pin has the new type of locking retainer, but I think it could still work. The bottom adjusting threaded pin would be our 21-002. The door uses three 21-004 and one 21-002 bi-fold pins.
